21 Lane-use arrow markings (see Figure 3B-24) should be used in lanes designated for the exclusive use of a turning movement, including turn bays, except where engineering judgment determines that physical conditions or other markings (such as a dotted extension of the lane line through the taper into the turn bay) clearly discourage unintentional use of a turn bay by through vehicles. Figure 3B-14 Examples of Applications of Lane-Reduction Transition Markings. 04 Examples of lane line markings are shown in Figures 3B-2, 3B-3, and 3B-7 through 3B-13. 15 If used, the diagonal or longitudinal lines should be 12 to 24 inches wide and separated by gaps of 12 to 60 inches. 13 For added visibility, the area of the crosswalk may be marked with white diagonal lines at a 45-degree angle to the line of the crosswalk or with white longitudinal lines parallel to traffic flow as shown in Figure 3B-19. When supplementing dotted lane line markings, a spacing appropriate for the application should be used. 09 The number of different word and symbol markings used should be minimized to provide effective guidance and avoid misunderstanding.

Stop and yield lines may be staggered longitudinally on a lane-by-lane basis (see Drawing D of. Staggered stop lines and staggered yield lines can improve the driver's view of pedestrians, provide better sight distance for turning vehicles, and increase the turning radius for left-turning vehicles. In advance of the point of divergence, a wide solid white line or normal solid double white line shall be extended in place of the broken lane line for a distance equal to the length of the diverging lines (see Drawing C of, If traffic can pass either to the right or left of the obstruction, additional white chevron crosshatch markings (see.

IDOT policy provides the direction necessary to provide a safe work zone while maintaining mobility. If used, the pattern of the raised pavement markers should simulate the pattern of the markings for which they substitute. 24 Section 3B.09 contains information about the lane line markings that are to be used for transition areas where the number of through lanes is reduced. These details will be updated on a continuous basis. At non-intersection locations, crosswalk markings legally establish the crosswalk.

Raised pavement markers also may be used to supplement other markings such as channelizing islands, gore areas, approaches to obstructions, or wrong-way arrows. 01 Retroreflective or internally illuminated raised pavement markers may be used as positioning guides with longitudinal line markings without necessarily conveying information to the road user about passing or lane-use restrictions. Yield (stop) lines and Yield Here To (Stop Here For) Pedestrians signs should not be used in advance of crosswalks that cross an approach to or departure from a roundabout. When pavement markings will be placed within the rumble strips, the marking material may seal the joint, making the fog seal superfluous.

Do Not Block Intersection markings may be used to mark the edges of an intersection area that is in close proximity to a signalized intersection, railroad crossing, or other nearby traffic control that might cause vehicles to stop within the intersection and impede other traffic entering the intersection. Edge line markings shall be placed on paved streets or highways with the following characteristics: Edge line markings should be placed on paved streets or highways with the following characteristics: Edge line markings should not be placed where an engineering study or engineering judgment indicates that providing them is likely to decrease safety. The following is a list of construction forms. 11 Because non-intersection pedestrian crossings are generally unexpected by the road user, warning signs (see Section 2C.50) should be installed for all marked crosswalks at non-intersection locations and adequate visibility should be provided by parking prohibitions. If authorized by law, Do Not Block Intersection markings with appropriate signs may also be used at other locations. On the approach to a multi-lane exit ramp having an optional exit lane that also carries through traffic, lane line markings should be used as illustrated in Drawing B of. 77 0 obj <> endobj 02 Edge line markings should be placed on paved streets or highways with the following characteristics: 03 Edge line markings should not be placed where an engineering study or engineering judgment indicates that providing them is likely to decrease safety.
